PIC 16F84A DTMF Repeater or Remote Controller

This PIC16F84a based repeater DTMF controller is very simple and economical to build. It also gives you hand-on experience of using and programming PIC Micro controllers. Controller measures 10cm X 6 CM and may be housed in your repeater project enclosure.

Object Detector using PIC16F877 and GP2Y0D340K

This is to try the Sharp GP2Y0D340K infrared object detector. It is cheap, the disadvantage is that is will detect an object but it has no indication of the distance of this object. The detection range is highly reflectiveness (thus color) dependent.

PIC12F675 8-PIN PONG

The prototype has power consumption of 0.5 mA running with the video cable disconnected from the TV set, and 4.5 mA when the cable is connected. So most of the power goes to drive the 75 ohm video line.

Variable flashing LED using PIC18F242

A simple project to get to know the 18F242. A flashing LED with the frequency controlled by a variable resistor. Turn left to increase the flashing frequence, turn right to reduce.

Very Accurate LC Meter based on PIC16F84A IC

This is claimed as a very accurate and simplest LC inductance capacitance meter. It allows you to measure incredibly small inductances starting from 10nH to 1000nH, 1uH to 1000uH, 1mH to 100mH and capacitance from 0.1pF up to 300nF.

32 x 120 dots graphic LCD interface using VK5121 module

Module VK5121 is made by Vikay. Some have an EL backlight. (for example the VK5121ELYG) These modules have two on-board SED1520F controllers. You'll need these routines to display text or graphics with a PIC16f877 or 18f452.
